A single wide-open eye, drawn in grey and white spray strokes with a bright highlight in the pupil and long runs dripping from the lower lid. The background is opaque black across the whole frame, so the wall gets a solid black square with the eye inside it rather than the drawing alone.

A wad3 file at 64x64 pixels: one pixel is one unit on the wall, and a CS 1.6 player is 72 units tall, so the black square lands a bit below shoulder height. The palette is nearly spent at 243 entries out of 256, which is what all the grey gradients cost, and nothing is transparent. It weighs 6,296 bytes, well under the 16 KB tempdecal limit. The page offered a raw 8-bit logo rather than a ready .wad, so the file was packed into wad3 on import. Two .url shortcuts were also in the archive.
